. Patented July 18, 1911.

To all whom it may concern:

Be it known that we, Orro PRonLss, of Kansas City, in the county of Jackson and State of Missouri, and WALTER S. HALL, of Argentine, in the county of Wyandotte and State of Kansas, have invented certain new and useful Improvements in Muriatic-Acid Tank-Cars, of which the following is a specification. 4

Ourinvention relates to tank-cars for the transportation of muriatic acid and other similar liquids by rail; and the objects. of

our improvements are: first to provide means for dividing the carload in order to reduce the momentum efiect'upon the car and tanks; second, to provide a yielding connection,- between the car and tanks adapted to reduce the -strainon the tanks caused by'the momentum when the cars are bumped together; and third, to provide an improved tank construction. We have attained these objects by the construction'illustrated in" the accompanying drawings in whichp 4 Figure 1' is a fragmentary side elevation partlyin section of a tank-car containing our invention, the truck being shown in .dia1.

' gram. Fig. 2-is a plan or top View of the same. Fig, 3 is adetail on an enlarged scale showing one of.the yielding fastening devices for attaching the tank to the, car platform.

It has been ascertained'that liquids heavier than oils cannot be practically transported in horizontal wood-lined tanks mounted onthe car platform lengthwise, for the reason that the momentum of such heavier liquids coming under shocks produced by bumping the cars together in the common manner, which is practically unavoidable in handling a train'of cars, will burst ends out of the tanks in a very short while. To avoid'this strain effect we provide a plurality of upright tanks A, preferably three in number, about eight feet. high, the. width of the tanks corresponding to the width of the cars, about-eight feet, and the three tanks filling the length of the car. By this means the load of acid may be divided into three comparatively short parcels each having a front area substantially equal to or greater than the transverse square of the car and reduced lengths of liquid .mass in which the hori; zontal motion takes place in travel. As a consequence, the divided load produces much tension by a lifting strain applied to said less strain upon the car-tanks than the con tinuous' load extended the full length of theca'r.

The tanks A stand slightly apart'upon the car platform and are secured thereto. by means of beams B which are centrally recessed to fit the outer contour of the tanks and extended across the car between the tanks to form a uniformly rigid attachment at the bottom of the tanks to the car where the horizontal strain between the car andbottom of the tanks falls when suddenly starting or stopping the car. A further means of securement of the tanks'to the car cOIlSlStS of preferably four brackets, a firmly attached to the outer side of the wall of each tank and supporting a threaded rod b which extends down'through an opening in the car platform and is.connected to a car-spring c, substantially similar to car-truck springs, which is set in a follower c and adapted to .be put under tension by turning either or both of the nuts on the ends of said rod in the appropriate direction.

The frame 0, in which the car-spring c is seated, is provided with flanges adapted to engage the under surface 0ft heavy longitudinal beams D of the cars so that said car springs may be put ',under increased rods 6, which hold-the tanks to the car platform. The rods 6 and their spring connection with the car platform afford a yielding resistance additional to gravity for holding the tanks down upon the platform. Such rod and spring connection is adapted to permit the tanks to'ti forward so asto lift the bottom sli htly from the car platform at the rear of the tanks in case of severe bumping, without damage to. the tanks or injury to their connection with the ca'r, and the'tanks, by gravity and the cooperation of said sprlngs, will drop back after such shock to their proper places on the car uninjured. V

A tank construction suitable for holding muriatic acid or the like in bulk for trans-' portation is shown in the sectional view at .the right in Fig. 1. It is made of an outer vessel E of sheet metal (boiler iron), an inner part E of wooden staves and heads which have been boiled in asphaltum, .and an asphaltum filling F between the metal and the wooden parts. The boiling of the staves and the heads E in asphaltum .fits

them to take thefilling 15 between them and the metal part henhot or in melted state so as to solidlyfill thespace Without forming bubbles therein. The Vessel E is pro- Vided with a rim flange 6 at the. top, and

cross timbers G are laid inside on the head to support a plank walk laid ontop of the tanks for thG bIZLkGmB/IL- Plugged openings tain the car-springs c beneath the car body substantially as illustrated and 1 described. Having described our invention What We claim is 1. In atank car of the class described,

the combination With the car body of a plurality o f' verti'cal tanks arranged apart from each other and lengthwise of the car body, cross-beams intermediate the tanks and secured to the car platfonnand Vereeaiao tically ielding connections of the tanks with the par platform, as and for the purpose speclfied I Y I V 2. In a tank-carer the class described, the Combination'with, the car body of a plurality of Vertical, tanks arranged apart from each other and lengthwise of the car body, vertically yielding means for securing the tanks to the carplatform, as and for the purpose specified. T3. In a tank-car of the class specified, the combination with; the car body of a and lengthwiseof the car, brackets spring ing from theexterior surfaceof the tankwalls, vertical screw-rods connected at their upper ends Withithe brackets, and springs secured to the car body'beneath the blackpluralityof upright tanks arranged apart ets and connected with the lower ends of said rods, and" means for putting said ver- 'tical rods under the tension of the springs, as and for the purpose specified.
